Respiratory failure & ventilation
A non-invasive method to monitor respiratory muscle effort during mechanical ventilation
Authors' conclusion
The study supports the feasibility of assessing respiratory effort during MV non-invasively through airway signal analysis.
Study context
- Population
- Patients on invasive mechanical ventilation (MV)epochs from 250 patients
- Participants
- 51,268 patients
- Comparison
- Non-invasive Pmus estimate correlated with Paw's pressure-time product (PawPTP) and VT
- Volume-control (VC) moden = 17,648 epochs
- Pressure-control (PC) moden = 33,620 epochs
- Outcome
- Correlation of PmusPTP with PawPTP in VC mode and with VT in PC mode
Main finding
As reported in the abstract
VC mode
0.91
R² · interval 0.76–0.96
PC mode
0.88
R² · interval 0.74–0.94
Further findings
R²
| Outcome | VC mode | PC mode |
|---|---|---|
| Negative control correlations (PmusPTP vs VT in VC; vs PawPTP in PC) | 0.03 | 0.06 |
